DESIGN AND FABRICAION OF METAL SPINNING WITH LATHE CARRIAGE

ABSTRACT This paper presents improvement in manual metal spinning process. The machine carriage is modified mainly for the purpose of reduction in requirement of a skilled workforce. The spinning machine consists of a mandrel mounted onto the headstock spindle. A work piece on which operation is to be performed is clamped in between this mandrel and the tailstock (dead centre). Final component formed by pressing blank over the mandrel. The operation is performed by a hand tool on a spinning lathe. It is tedious process. Lots of human effort required for this process. The metal spinning machine with lathe carriage is a modification of the manual machine. By using roller tool & lathe carriage aids to control the entire operation, in order to reduce requirement of skilled labour, to improve overall efficiency in the current process, improving consistence and repetitiveness along with an overall reduction in cost. Also in this we find out effect of roller tool radius on surface finish of final component. For trial purpose we design various roller tools & make modification in lathe carriage.
